Hello
I keep getting those errors, and I have observed it on another machine.
Here is the last one this morning for instance. It seems it is finally not related to shaders.
It seems similar to this one.

To give more details: we have a server with different offscreen renderers. Each renderer is always accessed only from one thread,  but we have several renderers running in parallel on different threads.

Any advice most welcome.
